Condom/Foreskin Question

I've recently noticed that when I put a condom on, my foreskin still rolls over the head of my penis and back. When putting the condom on, I have rolled my foreskin back but this does not help. I feel as if the condom is going to fall off, but I know for a fact it stays in place. What happens is my foreskin continues to move and bunches the condom up near the top. Therefore, the part of the condom that is on my foreskin goes "under". Like between my penis and my foreskin when it is rolled over the head. Think of a condom that is too long and bunches up in the middle. However, in my case, it is not too long and instead the foreskin folds over it. Maybe it is too tight/loose? Help? Its hard to explain lol.
